  1. There will be a gain, but hardly noticeable. The alternator is always striving to keep the battery charged, so the fuller the battery, the sooner the alt's load will be reduced. More and more cars have "inteligent" charging, ie the alternator only online when engine braking, unless the battery gets drained below a certain level.
  2. The battery will live a longer, healthier life if it is kept topped off. Also, trickle charging is healthier than forcing energy in with a higher current.
